The reason not have the tests normative is that they can often easily 
implicitly require behavior that is not intended to be required, without 
it being at all obvious. (In a spec it's usually obvious when that 
happens, since there has to be a "must" somewhere.)

Also, it's much easier for tests to implicitly require a particular model 
without that model being thought through than it is for a spec to do that, 
since in the spec anything not said explicitly isn't required.
